srncnuca'rxon r all whom i it may concern.-

Be ,it'known that I, WILLIAM R. DONALD- SON, of Chicago, inthe' county of Cook and State. of Illinois, have invented certain new and useful Improvements in Vehicle-Tires;.

- and I hereby declare that the} following is a full, clear,-and exact description thereof, reference being had to the accompanying drawings, which form part of this specification;

This. invention is' an improvement in vehiole-tires; and its object is to provide a preferably removable sand or'rnud tire'for vehiclewheels which isapplic able to ordinary vehicle-wheels to increase the breadth of the tread thereof when traveling oversof t, mudd y,

or sandy ground.

I The invention will be clearly.u'nderstood--. from the following description, taken in con-- 'nectio'n'wlith the accom panyingdrawings, and.

the substance of the'app'lication is set forth in iheclaims, following the description;

In the drawings, Figure lis an enlarged transverse section through the felly,'tread,

and tire of a wheel and through'what I now tire, .whir-h is removably applied thereto. Fig. 2.is-a'detail side view of-Fig. 1.;' Figs. 3 'and 4 are views similar to Fig. 1, showing modifications of the' auxiliary sand or mud tires.

- Referring to the drawings, a designates the felly of an ordinary wheel, 1) one of the spokes,

,d the grooved metallic tire-band, and 'e a cushion or pneumatic tire' ..of ordinary construction, such'as are commonly in use. wheels and tires are well adapted for service on'pave'd streetsand hard roads; but owing to the narrowness of their tread they cut.

deeply into sand and soft ground. Inorder to adapt the vehicles for use over soft ground, it has been proposed to provide them with cushion or pneumatic tires of large diameter; but these latter are very expensive-and troublesome, and while advantageous in -sand they are not so desirable on hard roads.

In order to enable the vehicles tobe used in soft, inuddy,--or'sandy ground, I provide an auxiliary sand or inud tire, which is applied to the rim of the. wheel over the ordinary tire and is preferably d'etachably fas-.

tened tothe wheel in any suitable manner.

Such

Serial-No. 18,433. iNo mam in Fig. 1 the au'kiliary tire'is' shown as consisting of a flexible or resilient 'bandjor annulus fiadap'ted to fit overlhe tire e. 'Onthe opposite 'edges'of {this band are'circl'lmfereniial cushions g, which fit on each side of'thetire e and greatly increase the width-of the .treadof the'wheel. These cushions g, ifdesired, may be made-hollow, s o 'asjto form pneumatic cushions, and, as 'sh'own,'th'ey-'are provided with air-fillingvalves h. -When= the "auxiliary tire isnot to be 'used,'th e cushion vg can be deflated and the tire'can-becollapsed into small space. 1 When it is to beused, it is'applied over-the tire eof" the wheel, as indicated, and thenthe cushions tif pneumatic) may be-inflated". The auxiliary tireimparts a'firm but. resilient and'broad'-bearing-su'r-- face or tread to the wheel; whichwill enable it to travel easily over soft sandy roads. The

auxiliary tire may be detachablyseeuredto the wheel inany desired mannen vanous ways being illustrated in-the drawings.

In Figs. '1 and 2, for example, the cushions g are provided with eyes 11, through-which are considerlthepreferred form of sand or mud.-

passed leather straps provided with buckles it, by which they can be readily fastened over the felly, so as shown.

to hold the auxiliary tire, as In Fig. 3 the construction is substantially as alreadydescribed, with theex'ception that the opposite pneumatic cushions g are provided with inwardly-projecting shoulders Z,

.which when the cushions, are inflated will .bind'c'losely against the felly d, which latter.

maybe provided with recesses. to receive the lobes, or, as shown, the flanges of the tireband (1 may be bentv outwardly to; form lips m, engaged by the shoulders [to secure the.

auxiliary tire in place. For the purpose of lightness the auxiliary tire may also be provided with annular passages 0,which 'canbe.

inflated with air, if desired.

Instead of one band provided with two cushions I may employ two bands pand r, as

shown in Fig. 4, respectively.provided'with As shown, the metal. stranst are used, one end-of each, of such str aps besingle cushions qv and s. In applying these 5 to a wheel band 1) is first laid over the tire e.

IOO

ing fastened to the loop u on cushion q, and its other end is fastened by means of a strap v to a buckle w on cushion s, so that the parts ,will be securely held in place.

As Various changes may be made in the form and construction of the auxiliary tires,

and particularly in the fastening devices thereof, within the scope of my invention, I do" not limit myself to the specific constructions herein shown. I A

Having thus described my invention, what I claim as new is' 1. The combination with a vehicle-wheel,

, of adetachable mud or sand tire wider than the wheel tire and provided 'with opposite cushions projecting on oppositesides of the wheel-tire, substantially as described and for the purpose set forth. j

2. The combination of a vehicle-wheel with .a detachable sand or mud tire adapted to fit around the wheel and provided with inflatable cushions at each side, substantially as described.

3. The combination of a vehicle- -v neel, with a'saud or mud band adapted to fit around the 'wheel and provided with cushions at each side of the wheel-tire, and means for detachably fastening the band in place around the.

wheel-tire, substantially as described.-

4. The combination of a vehicle-wheel,with

a' detachable sand or mud band therefor adapted to fit around the wheel and provided with inflatable cushions to fit on opposite sides collapsible band adapted to fit over a wheel tire and having annular inflatable cushions on its edges, substantially as described.

7. The herein-described detachable sandband or auxiliary tire for vehicle-wheels conisisting of a collapsible band adapted to fit over a wheel-tire and increase the width of its tread, and means for securing said auxiliary tire to a vehicle-wheel, substantially as described.

8. The herein-described detachable sandband or pneumatic tire for vehicle-wheels consisting of a collapsible band adapted to fit over a wheel and having opposite annular inflatable cushions adapted to fit against opposite sides of a Wheel-tire, and means for de- 'tachably fastening the same to a wheel.

9. The combination with a vehicle-wheel, of an auxiliary flexible resilient tire detachably secu red to the tire of the wheel and having opposite annular cushions adapted to project beyond and fit against opposite sides of the wheel rim or tire.

10. lhe combination with a vehicle-wheel, of a flexible auxiliary tire det'achably secured to the wheel and having annular cushions on its edges adapted.to fit against opposite sides of the wheel-rim, and means for inflating said cushions. v I

11. The combination with a vehicle-wheel,

of a flexible resilient auxiliary tire detachably secured to the wheel and havingopposite annular cushions adapted to fit against opposite sides of the wheel rim or tire, means for inflating said cushions, and means fordetachably securing said auxiliary tire to the wheel, all substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own'I affix my signature in presence of two witnesses.
